Tightening- windows



THOMAS SILVER,A OF' PHILADELPHIA, PENNSYLVANIA.

TIGHTENING WIND OWS.

Specification of Letters Patent No. 11,092, dated June 13, 1854.

To all whom may concern Be it known that I, THOMAS SILVEM of Philadelphia, in the county of Philadelphia, State of Pennsylvania, have invented a new and' Improved Mode of Tightening Windows, so as to Prevent the Shaking or Lateral Motion of the Sash, and thereby Prevent Any Noise or Battling of the Same; and I do hereby declare that the following is a fulland exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

The nature of `my invention consists in providing an inclined plane for the lower bearing of the sash of the window with a swell or projection in the window frame or casing forming a lateral bearing of the sash; these two producing an opposite bearing of the sash on the window frame or casing near the top of the sash, which bearings tighten the sash when in place and thus prevent it from shaking and producing any noise or rattling. It may be applied alike to windows `in omnibuses, coaches, carriages, stages, rail-road cars or vehicles of any other description, also to windows used in canal boats, steamboats, and ships, and also to windows in permanent buildings, such as dwellings, stores, warehouses and other similar buildings, my invention being intended to apply to windows in whatever instance they may be used.V

To enable others to make and use my invention I give the following description thereof, which will be understood by reference to the annexed drawing.

Figure 1 represents an elevated or front view of a window. 2 is a sectional viewv of a window frame or casing similar in some respects to those ordinarily used in coaches which forms the grooves or ways in which the window slides.

A, A, Fig. 2, is a sectional view of a window sash showing the position of said sash when the window is bot-hv closed and opened.

At B, B, Fig. 2, are two inclined planes which form the lower bearings for the win` dow sash.

At C, C, Fig. 2, are swells or projections inthe window frame or casing which are intended to form a lateral or horizontal bearing forthe sash.

It will here be seen that when a window sash is placed in either its upper or lower position resting on the oblique base B, B, Fig. 2, and against the lateral bearing C, C, Fig. 2, its own weight will cause its top eX- trelnity to press against the opposite side of the groove or slide at D, D, Fig. 2, thereby preventing any lateral motion or oscillation. The angle of bearing at B, B, Fig. 2, may be raised to suit practical purposes. An adjustable screw or other device may be used to regulate the swell or bearing at C, C, Fig. 2. An o-pen seam or slit may be made in the margin of the sash as represented in Fig. l, say from E to H (or other greater or less length), in order to relieve the glass or other substance used in the sash from the pressure or binding eifect produced by the lateral bearing atC, C, Fig. 2.

What I claim as my invention is- The swell or lateral bearing C, C, Fig. 2, in combination with the oblique base B, B, represented in the drawing, applied in the manner and for the uses and purposes herein described.
